Does this schismatic seminary of the excommunicated hand out doctorates in disobedience? Appoint revolutionaries as rectors? Use the services of excommunicated bishops to ordain other eccentric ecclesiastical oddballs who wouldn't be able to find the actual Roman Catholic Church with the actual Pope St. Pius X as their guide? He should only be with us today to nuke the group that dares misappropriate his name.
Why should the Vatican be any more concerned with SSPX seminaries than with Unitarian seminaries (if any) or Episcopalian seminaries or Islamic seminaries (if any)? None of these are Catholic and none intend to be Catholic on the evidence to date, regardless of their respective ancestries.
Through the intercession of St. Dymphna may Our Lord shower you with graces!
